Overwatch player Pvthazard uses an Oasis bug to lead Roadhogs into traffic. You can find a video of it here.
YouTuber Pvthazard found a bug in the new Oasis map. If you shoot a Roadhog while hooked, the hook doesn’t retract anymore. After this discovery, the next logical step was, of course, to create a complete team of NPC Roadhogs and walk them like little pets on a leash.

As you can see in the video, Pvthazard didn’t just want to take a walk and enjoy the sunshine. His intentions were sadistic in nature. With D.Va, he took the Roadhogs on a leash. They followed him so faithfully and innocently, unaware of the cruel fate that awaited them. Pvthazard led them on the hook to a busy road and turned his loyal entourage into Roadhog pizza!
Pvthazard watched the carnage from a safe distance. A few Roadhogs still tried to shoot at him in a last defense. However, they could not escape their death.
The cars on the Oasis map are not only popular because you can make Roadhog pizza with them. Players are already asking for kill cams.
